We want audio to be free from any kind of distortion.  If we play our recording with full volume it should not sound distorted. To ensure this we will be using the hard limiter option . This option trims high peaks of an audio clip and lowers it to match the lower peaks.

Go  Effect menu and click the drop-down button located at the bottom to find the Limit option. Some versions of Audacity show Hard Limiter in the drop-down menu without clicking the arrow.

A window will pop up that says ‘Audacity needs the file lame_enc.dll to create MP3s’.

Click the Browse button and locate the lame file  you downloaded earlier. Select the lame file and click Open. Finally click OK in the previous window. Your audio clip will be successfully saved into a mp3 file.
